Send emojis with SMS
You can send emojis too, of course, in your SMS.
The recipients phone will determine what and how your emoji will be displayed, not all phones will support all emojis.
If you send from your email, you can copy the emoji you want from the column "Brow" in below link.
If you send from API, you use the code in the column "Code".

Also, please note that a normal SMS can contain 160 characters, but when you send emojis the format is converted to Unicode and then only about 70 characters will fit.
This can cause your message to be divided into more messages than you might have anticipated. You can redan more about the length of SMS here.
